The opacity of the colored rectangles.
Opacity
The blending mode to use to composite the checkerboard pattern on top of the original layer. These
Blending Mode
blending modes work identically to the ones in the Timeline panel, except for the default None mode, which renders
the checkerboard pattern only.
Circle effect
The Circle effect creates a customizable solid disk or ring.
This effect works with 8-bpc color.
None creates a solid disk. The other options all create rings. Each option corresponds to a different set of
Edge
properties that determine the shape and edge treatment of the ring:
• The difference between the Edge Radius property and the Radius property is the thickness of the ring.
Edge Radius
• The Thickness property sets the thickness of the ring.
Thickness
• The product of the Thickness property and the Radius property is the thickness of the ring.
Thickness * Radius
•
Thickness & Feather * Radius
ring. The product of the Feather property and the Radius property is the feather of the ring.
The thickness of the feather.
Feather
Inverts the matte.
Invert Circle
The blending mode used to combine the shape and the original layer. These blending modes behave
Blending Mode
like the blending modes in the Timeline panel, except for None, which displays only the shape, without the original
layer.
Ellipse effect
The Ellipse effect draws an ellipse.
This effect works with 8-bpc, 16-bpc, and 32-bpc color.
Eyedropper Fill effect
The Eyedropper Fill effect (formerly the Color Picker effect) applies a sampled color to the source layer. This effect is
useful for quickly picking a solid color from a sample point on the original layer or picking a color value from one layer
and using blending modes to apply this color to a second layer.
This effect works with 8-bpc color.
The center of the sampled area.
Sample Point
The radius of the sampled area.
Sample Radius
Which color values are sampled:
Average Pixel Color
•
Samples the average RGB color values, excluding the color values of transparent pixels.
Skip Empty
•
Samples the average of all RGB color values, including color values of transparent pixels.
All
•
Samples the average of all RGB color values, premultiplied with the alpha channel.
All Premultiplied
•
Samples the average of all RGB color and alpha channel values. This setting results in the sampled
Including Alpha
color also containing the average transparency of the sampled pixels.
The product of the Thickness property and the Radius property is the thickness of the
